SPECIFICATION forming part of Letters Patent No. 289,928, dated December11, 1883.

' Application filed August 17, 1883. (No model.)

T0 @ZZ whom it. may concern,.-

Be it known that I, Aivros F. PARKHURsT, a citizen of the United States,residing at Kewanee, in the county of Henry and State of Illinois, haveinvented certain new and'useful Improvements in Bottle-Stoppers, ofwhich the following is a full, clear, and exact description, referencebeing had tothe accompanying drawings, making part of this specication.

`My invention relates to that class of bottlepers,77 wherein the valveor stopper proper closes upward, and is operated by a bail or handleprojecting up in the neck of the bottle.

rIhe novelty consists in the combination,y with the neck of a bottlehaving a slightlycontracted throat at or near its middle lengthwise, ofaninternal stopper-plug having a looped wire bail rigidly fastened byone end to the plug or valve, and having the other end free, whereby thebail becomes a spring to hold the plug or valve in either its closed or`open position, as will be herewith set forth and specifically claimed.

In the accompanying drawings, Figure l is a vertical central section ofthe upper part or neck of a bottle provided with my improved stopper,showing the valve open. corresponding view, showing the valve closed.Figs. 3 and 4 are modifications in the springbail.

A represents the neck of a bottle whose throat is slightly contracted ator near the point of the dottedline a. rIhe valve or plug B, I prefer tomake of the two integral or separate disks b, with an intermediateprojecting rubber disk, as is common in this class of Stoppers.

Extending .up from the valve B, and rigidly secured thereto by one end,is the spring-bail ,0, which may be of either of the forms shown inFigs. 1, 2, 3, and 4. This bail is formed of wireso bent and doubledback in the neck of the bottle that its upper end forms agraspingloop-for drawing the f stopper up to its seat, while its freeend serves as a spring, which,

Fig. -2 is aactingagainst the throat of the neck, in connection withthat part of the outward bend of the bail just above its point ofconnection and opposite said free end, serves to hold the valve ineither its open or closed position, as shown in Figs. 1 and 2. Thespring is sufciently yielding to pass throughv the contracted part ofthe `throat of the neck, while the upper bend forming the grasping-loopis` sufficiently large to prevent the stopper falling entirely into thebottle.

In Figs. l and 2 I have shown the bail bent in substantially the form ofa figure 8; but the forms shown in Figs. 3 and 4 serve the samepurpose,'and I consider them as equivalents.

The advantage of having a stopper which can be held either open orclosed, as above, is that it can be used with still liquids as well asgaseous or aeratedliquids, and when the bottle is tilted to pour out thecontents there is no liability of the stopper accidentally rer seatingitself.

I do not limit myself to the shape of the bail,

nor to a bottle with a contracted portion in its throat or neck, for aspring-bail properly fitted intoa straight neck would serve to suspendthe stopper adjustably by the frictional contact caused by the spring inthe bail. I do, however, limit myself here to a bail attached rigidly tothe stopper by one end only and l with the other end free.

- Having thus fully described my invention, I claim- Y rEhe combination,with the neck of a bottle,

of an internal stopper provided with a laterally-yielding spring-bailformed of a continuous piece of wire, rigidly secured by one end to thestopper and located in and so arranged as to act inconjunction with theneck of the bottle to hold the stopper suspended in either an open orclosed position, substantially as described.
